“…In non-ionic polymer solution by adding anionic and cationic surfactant increases the lower critical solution temperature of the polymer was reported [5]. According to Andrzej Dworak [6], the degree of the substitution of the hydroxyl groups with the acetate groups influences the solution behaviours of the obtained copolymers, the cloud point may be controlled between 4°C and 100°C. Freund and Dobias confirm in the case of quartz flotation using cetylpyridinium chloride (CPC) as the collector a decrease of quartz floatability with CPC concentration higher than its CMC [7,8].…”

This investigation involves the effects of non-ionic surfactant materials on the industrial sodium oleate, sodium naphthenate and their mixtures at different temperatures by the surface tension methods. The effects on the critical micelle concentration (CMC) of sodium oleate were assessed by the Toween 80(T-80) presence, polyethylene glycol, polyether and other non-ionic surfactant. T-80 was proved more effective than other non-surfactant in increasing the sodium oleate CMC at same concentration. Using the optimal composition of sodium fatty acid and the surfactant can reduce the temperature of separation hematite from 43°C to 23°C, achieve the purpose of low carbon and energy saving.

Stimuli‐responsive materials have received considerable attention for their application in biomedical fields. Herein, the temperature‐dependent phase transition behavior of acetylated polyrotaxanes (Ac‐PRXs) consisting of acetylated cyclodextrins threaded onto a linear axle polymer in aqueous solution is investigated. The aqueous solutions of Ac‐PRXs exhibit temperature‐dependent transmittance changes when the degree of acetylation is 30–40%. Upon increasing the temperature, Ac‐PRXs are dehydrated and acetyl groups are subsequently associated through hydrophobic interactions. Interestingly, the Ac‐PRXs form coacervate droplets with a diameter of ≈2–3 µm above their cloud points. These temperature‐responsivities of Ac‐PRXs are observed for other PRXs with different axle polymer molecular weights and compositions. Consequently, the acetylation of PRXs is an attractive chemical modification for yielding temperature‐responsivities, and Ac‐PRXs can be applied as temperature‐responsive supramolecular materials.
